Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a device for simply testing the permeability of concrete. Background Art

[0002] Concrete quality inspection can be divided into three aspects: intrinsic quality (compressive strength, flexural strength, frost resistance, impermeability, chloride ion permeability resistance and steel bar protection layer thickness, etc.), surface quality and dimensional quality. When evaluating the performance of concrete, permeability is an important indicator. There is a close relationship between concrete permeability and durability. Good sealing is required when testing the permeability of concrete.

[0003] The Chinese patent publication number CN220063763U discloses a device for testing the permeability of concrete. When testing concrete, a concrete block is placed in a placement groove, and then the motor drives the pressurized panel to move downward, so that the sealing plug seals the placement groove.

[0004] However, when the pressurized panel drives the sealing plug into the placement groove, when the concrete is not placed in the center of the placement groove, the side of the concrete block that fits the placement groove blocks the sealing plug from entering the placement groove, thereby reducing the accuracy of the single concrete permeability test.

[0005] Moreover, after the device is used, dust easily contaminates multiple water level displays, resulting in the need for manual cleaning when the concrete block is tested next time. Therefore, it is necessary to propose a simple device for testing the permeability of concrete to solve the above-mentioned problems. Summary of the invention
